I am trying to solve an inorganic chemistry homework that basically demands a proposition for a catalyctic cycle mechanism that will catalyse the following reaction:
+ 1/2 O2
We are also required to use a metallic complex with Rh as the core, Br and CO as ligands.
I think we need to oxidize the SO2 to SO3 using the 1/2 O2 in the process and react the resulting SO3 with H2O to obtain H2SO4.
Like in the following figure from Atkins:https://imgur.com/m5hlnf1
I also though of:
- Migratory Insertion (especially regarding CO, but this doesn't go anywhere because there is nothing organic)
- Oxidative Addition / Reductive Elimination (This may be useful during the addition of O2 to make Rh go from 16 electron +I state to 18 electron +III state)
- Ligand Substition
I also looked closely at Wilkinsons and the below one: https://imgur.com/fwkB3mc
However, I cannot devise anything it has been at least 8-9 hours! I am really frustrated and would appreciate some help. Thank you.
